Biodegradable Plastic Part 5

now with microscopes

Overview

note: all samples were initially left in a window for a period of 3 weeks before all further testing shown in these results. all further sample testing took place over the same 7 day period 

I did this multivariable experiment to try and understand what results in the creation of bioplastic most similar and and strong to that of traditional plastic 

Sample A: on a window sill

Sample B: blended on a window sill

Sample C: submerged in water

Sample D: outside on a table in a bag

Sample E: outside on a table fully exposed

Sample E2: E then heated to 300 degrees for ~4 minutes

-E and E2 are far better then all other samples

-E has a hard structure and appears only slightly clear. it breaks over light amounts of force 

-E2 has a much much harder structure then E is a non clear white and only breaks under heavy force 

-There seems to be a direction relationship between the strength and hardness of a sample to it's glow under a ultraviolet black light 
(note that spooled PLA is also very reactive under ultraviolet light) 

-I have no idea why this occurs relationship occurs and i cannot find any public academic paper relating to or mentioning this subject.

-E is quite flammable and emits a slow cracking sound as it burns into a dark ash very similar in texture to a biochar.

-overall E2 (full name: 4-E2) is the best by far, but more research needs to understand why and how it occurs in such an outdoor environment and how to refine it in a  consistent process that can be replicated by others.
